Calendar Grey December 6, 2022
Dist Redhat Esm H88
Explore the Red Hat notification regarding a moderate dbus security patch that resolves critical vulnerabilities in RHEL systems.
An update for dbus is now available for Red Hat Enterprise Linux 8.6 Extended Update Support

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all running instances of dbus-daemon and all running applications using the libdbus library must be restarted, or the system rebooted.

Summary

D-Bus is a system for sending messages between applications. It is used both for the system-wide message bus service, and as a per-user-login-session messaging facility.
Security Fix(es):
* dbus: dbus-daemon crashes when receiving message with incorrectly nested parentheses and curly brackets (CVE-2022-42010)
* dbus: dbus-daemon can be crashed by messages with array length inconsistent with element type (CVE-2022-42011)
* dbus: `_dbus_marshal_byteswap` doesn't process fds in messages with "foreign" endianness correctly (CVE-2022-42012)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
